Whether this was scripted or not, CM Punk is absolutely right with everything he says.
I don't know if he is going to leave after the Money In The Bank PPV or not. I have a feeling he may want to return to ROH, but Vince and the WWE should be doing all they can to keep CM Punk. He is the most talented wrestler they have on their roster and he is the best at cutting promos, he knows this himself, I'm sure most of the WWE locker room know this and after reading a WWE forum to see the general reaction to this promo, it seems the majority of WWE fans recognise this as well.
This guy could be huge, I mean on the level of Stone Cold, The Rock, Bret Hart, HBK etc and the WWE need to recognise this and do all they can to keep him.
